Clamping force equations for this piece

[goodguy1405]

Does anyone know how I would calculate the clamping force of this piece? It is Stainless Steel.

Is there a picture of this piece?.

I tried to add it. Let me try in here.

Sorry the picture doesn't have any dimensions and only one view I have no idea what your showing us.

Here is some more pics let me know what I am missing. Thanks for your help.

Ah Right its a shaped spring, so what are the material properties or grade of material?
What deflection of the clip are you looking for and what force do you require?

It is a stainless steel material (the shaped spring). I am not sure what deflection I am needing or force. I want it to be about the same force of a potato chip clip. I cannot find anything about potato chip clip force or deflection online. Thanks for all your help

hi

Well you need to calculate the stiffness of the spring first off with the dimensions you have, WR Berry's book on spring design has a very good graphical method of calculating the stiffness of springs similar to the one you have posted.

Once you have the stiffness you need to get your deflection and force sorted and then you can select a appropriate material.

I do not have that book. Do you know where I can view just that page in question?

Hi

try googling the book on line it should be fairly cheap to buy but you might get a free preview.

how critical is this to know ? can you build it and measure the stiffness ? maybe build a prototype test piece ??

how critical is spring force ? 10% tolerance, 1% ?

are the parts very reproducible, or will you need to test and modify each one to get the result you need ?

another day in paradise, or is paradise one day closer ?
